Specification of Letters Patent.

Patented May 28, 1918.

Be it known that I, EDWARD B. Hess, citizen of the United States, and a resident of the borough of Brooklyn, in the city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Type-Writing Mas chines, of which the following is a specification.

The present invention relates generally to typewriting machines and has more particular reference to a new organization of the printing elements and the margin controlling devices.

Margin controlling devices, as such are, of course, well known in the art and as heretofore constructed, they may be classified under three heads. In one Well known type'cf margin control, the carriage is in the render a margin controlling device visible at all times to the operator without mterform of a hollow square or rectangle'in which. the platen is supported about midway ot the machine between the front and rear thereof, the margin rail being located in front of the platen but separated therefrom b a considerable distance. In this type of construction, the margin rail and its stops are mounted on the carriage and travel therewith and a single element for cooperating with the stops on the rail is located on a stationary part of the machine: or, the margin rail and its stops are mounted on a stationary part of the machine and a single stop element mounted oil-the movable carriage. This type is generally used on machines of the socalled blind type but even in that type it renders the carriage construction imwieldy; and, when applied to visible typewriting machines the construction manifestly interferes-with full visibility of the parts. c

Another form of construction heretofore used in the artis exemplified in what is known as the top strike machine in which the iargin stops are carried directly upon the rail or track on which the carriage travels: or, in which the margin rail and its stops are closely adjacent to the rail of the; carriage. in both of these cases the margin rail and stops are located under the; platen and in a very inaccessible position. A third construction of margin controlling device is exemplified in the well known loval typcwriung machine in which they in rail and stops are located in rear of the platen and beneath the paper table. This location is advantageous in that it gives full visibility but has certain disadvantages which may be briefly summarized as follows: In order to effect adjustment of the marginal stops, it is necessary for the operator to raise the paper table and, when the desired adjustment has been effected, to replace it. Consequently, the adjustment to which the margin stops has been set is not constantly under the eye of the operator. Furthermore, the location of the margin rail on the carriage in the place indicated necessarily increases the width of the carriage and renders a nice balance of it ditfi, cult due to the fact that all of the additional elements are located substantially in rear of the platen which results in an uneven distribution of weight.

wT he main objects of this invention are to fering with the am visibility of the printing point, to reduce the weight of the carriage and to facilitate the balancing of the c parts of the same.

ll he main feature of the invention resides in arranging the margin controlling deyices adjacent the printing point in such manner that the type bars have unobstructed passage to the platen and without interferingxwith the full visibility at the printing 1)Ol[l this being accomplished by coiirdihating said margin 'controlling devices with the other elements of the machine.

In theoreferred form of the invention as hereimdisclosed. the margin controlling devices consist of two rails adjacent to the printing ,ipoint one rail being located on each sidei thereof so that suilicient space is ati'ordedim travel of the type bars to and from the platen. lnthe particular form in which the inventioniis herein clothed, the margin rails are located in front of the platen below a horizontal plane through the axis thereof. Each rail isprovided with a stop element projecting rearwardly toward the platen; and the platen is provided at each end with .a forwardly extending stop clement cooperating with its complementary stop element on the margin rails. In connection with these devices there is utilized indicating scales, conveniently carried by the rails, said scale-s being distinguished from those now employed in that the highest numeral is m: the left hand end of each in elevation, partly in section and partly broken away, and with elements omitted to illustrate the relation or the righthand margin controlling devices to the bell ringin and line lock mechanism and margin release mechanis. the parts being shown in the position they normally occupy, except that one type bar shown in printinn" osition.

To link 1% is secured a bar or link 15, the rear end of which is bent to engage e universal bar 1%, link 15 being provided with a spring 1 7, the rear end of which is connected with an adjustable rocking frame 18 and the front end of which is secured to a member 19 carried by link 14. It will. be understood that all the type bars, when actueted, move to a common printing point or center. Adjacent to the common printing point of the machine is a type bar guide 20 consisting of two converging members suitably mounted by means or". the bracket 21 on a stationary part of the machine. Mounted to more Witl'i the carriage race way 2, so as to partake of the case shifting movement imparted thereto, is a ribbon vibrator '22, a front card guide 23 and its scale 24:. These elements are also located adjacent to the printing" point and are intermediate the type bar guide and the platen. Enclosing the upper part of the machine are the dust sheds carrying the ribbon spools 26.

indicates a margin rail located on the left-hand side oi the common printing center, and 538 indicat s another marginrail located on the right-hand side of the common printing center. These margin rails are conveniently sugported, in this instance, on top of the dust sheds 25 in front of a vertical line and below a horizontal line drawn through the axis oii tl1e platen; below the normal position occupied by the ribbon vibrator and in front thereof, and lso in front of 0 card. tllle and its scale. In fact the L n irgin rails, as here shown, are located in rent of a vertical one tangent to the front face of the platen, and below a horizontal line tangent to the underside of the platen. It willelso noted that the margin rails "Jove the series of type bars. and over substantially in line with the pivots of ssocieted with the right-hand margin is a stop element 29 adjustably mounted ."eon and a stop element or block 30 noted on the carriage, Said right-hand margin rail 28 is provided with pivot extensions tl'iatproject iito suitable bushings 32 in e. stationary part oi. the framework so that sai d margin rail is in efi cct a rocking member. Extending from the lower side of rail is a dependent controlling member 33 having at its lower end an L-shaped SlLl Bl consisting of a horizontal portion 35 and a vertical portion A spring 37 attached at one end to the dust shed and at its other end to toe controlling member normally In this case therefore the inin'in the 1 gea 6 my means mm 15 normally ur and 11a:

' ima is in memes the horizontal portion 35 of slot 34: and admitting of further manipulation of the key levers. It is evident that, as soon as the key levers are so operated, the carriage thereby moving to the left, cam will disengage cam 63," and the controlling member 33 and margin rail 28 will be restored to their original position by action of spring 37, this movement also-causing connection to to be seated again in the vertical portion 36 of slot 3st. It is also evident that, if margin re lease rod 49 is operated and the controlling member 33 is permitted to descend during further manipulation of the key levers, gong 5% will strike bell 52 a second time. The carriage can, of course, now be advanced to the left until the stop element 30 comes in moved to the right, past the cam members o and 62, without effecting any tilting movement of the margin rail 28 and without I operating bell and line look, but that, owing to lugs 68, the movement of the carriage to the left will be interrupted, as previously de scribed, by the coiiperation of the stop elements 29 and 30. The cycle of operations has been described in connection with the "upper cam member 65 of the stop element 30. This is the cam that will be in operative p sition when the carriage and platen are in their lower case position, as indicated, for instance, in Figs. 4 and 5. Should the carriage and platen have been moved, however, into upper case position, as indicated in Figs. 7 and 8, then, it is evident, the cam surface 6& will engage with cams 62 and 63 in precisely the same manner as previously described in connection with 65? It will be understood that the upper and lower cam Iniembers 64 and 65 are necessary when the invention is used in a machine having a verticalpase shift. In view of this construc tion. howeyer, it is necessary to make allowance for possible case shift by the operator when the stop member 80 is in engagement with cam member 62 or 63.- that is, approximately in bell ringing or line loch positionl, It will be observed, that. should it be attempted, when the parts are in hell ringing position, to shift from lower to upper case. elevation of the carriage will talre place but engagement of can 65 with the underside of cam 62 will cause tilting of the margin rail 2 to such extent that the line lock will be actuated through the controlling member 33 and its connections, so that'it will not be possible to bring the type bars to the printing position. Also, that the ease shifting movement of the carriage into elevated posithonwillbe permitted to its full extent without "placing undue stress on the margin rail or line loch position, the lowering of the arniage will cause the tilting latch 65 to be displa ced inwardly and case shifting will be effected (see F .12). l Vhen the parts are in line lock position, the shifting from upper to lower case has the additional function of are-leasing the line lock mechanism since the rocking rail. 28 is immediately restored to its position by the action of sprin 87.

,- The left hand margin railfii is provided with vertical teeth or notches, as shown, and is ada ted to support an adjustable stop element 4 that cooperates with a stop element 7;; on the transversely movable carriage. The stop element 7% consists of a carrying member 76,,"slidably engaged. on the rail 27 and is provided with'a stop dog 77 consisting, in effect, of an adjustable screw. 78 indicates a pawhthe point ofwhichenters the notches of the rail 27 and is provided with ears 79 overlying the upper and lower side of the carrying member 76". Formed in said ears 7 9 are slots 80 into which'extends a pin 8]. on the carrying member 76, the pawl being normally urged into engagement with the notches on rail 27 by means of coiled spring 82 surrounding pin 81 said spring engaging with one end on" a portion of the pawl; 7 8 and with its other end on the carrying member 76. The pawl 78 is further provided with a handle or operating member 85$, as shown. When thehandle is depressed against the action of spring 82. the point of pawl 7 8 becomes disengaged from the notches in the margin rail 27 and, simultaneously therewith, the carrying member is moved to the left so that pin 81 occupies a mid-position in slot 80. ll hen the pressure on handleSS is released, the end of pawl 78 enters the notch in rail 27. the pin 81 meanwhile remainiug substantially in its mid- *position; in slot 80. When thereafter the stop eleinent on the carriage engages the stop dog Y7. as the carriage is moved to the right, the carrying member 76. and with it the dog 77. is moved to the right a distance egual. substantially. to one letter space, its position being determined by the engage ment of pin 8i with the end of slot 80, as shown more parti ularly in Fig. 1, thereby bringing the carriage to the right to the extreme limit of which the adjustment of the outer end I hevei sun th e corresponding I m) eiement in the eits and T5 is al Wh the? or not "o or upper 111C cerrieti h "he oiiowing "foi'in. c provided 'pivoteiiy supported on horizontal axes 96 springs 9?, into an upright position against the stoo pins 98 so that when the carriage :1 st form of the invention and will succestiit margin rail 2 en, however, the careiege is moved to the right With the stop eiement 99 in e position between the dogs 95 and the peinting centeiyit is evident that said dogs niii yield when encounterech as inciiceteci in dotted lines, and will admit of the unciist rbed passage of the carriage to the night.
